‘Why Knot?’ A Kinetic Sculpture That Ties and Unties a Necktie in 350 Steps

“Why Knot?” is a kinetic sculpture that uses an array of gears, arms, and motors to continuously tie and untie a necktie. The entire process involves 350 steps and takes nine minutes. Artist and retired engineer Seth Goldstein spent five years perfecting the machine, which he finished back in 2005. The Washington Post has more on Goldstein and his sculpture.
